Add extra requirments to giveaways!

You can do that, from a private giveaway and moderator approval.

EDIT: Not that hard. I hope it's in the FAQ somewhere.

That's actually...a very good idea if I'm honest. Conditional requirements based on achievements...It would mean that you're able to know the person actually plays the game a reasonable amount for a DLC, for example, or as you said completed a predecessor...Or even just a fan of the genre of game if you could set multiple achievements, with a setting to say Achievement 1 or Achievement 2, for example...

And all this lies within steam community, which is already accessible by steamgifts, as that's how we check if you have the game in the first place...Not a bad idea at all...

Just make it as private and invite who fill your requirements ^^

"to be aple to join the giveaway." oops! small typo :)

That idea just sucks In my opinion.
Let say that I have for example Batman Arkham Asylum on Retail DVD and I want to enter a Batman Arkham city give away, but I don't have the first one on Steam.
What would I do? Buy the first one on Steam, that I already have on Retail JUST to enter a giveaway that I might not end up wining?

This Idea is not a good one. Keep that for Private Giveaways.

I see 2 problems with this:

1) He may have a non steam version of the first game.

2) He played the game in off-line mode (achievements don't unlock in off-line mode).

While I see this as a good idea, it's flawed as well.

For example, someone like me who couldn't get their hands on Deponia yet could want to enter for Chaos on Deponia and not play it until after they've played Deponia.

Before you say anything, there's video reviews, demos, etc so someone could know they would like the game without having played the predecessor.

And how would the achievement(s) required be controlled? If it has to be human control it's a bother to the mods who already have enough work as it is and you can also get the same result from doing private giveaways with approved rules.
